B class
Tripping is ensured for sinusoidal AC
residual currents pulsed DC residual
currents,alternating residual sinusoidal
currents up to 1000Hz,pulsating direct
residual currents and for smooth direct
residual currents,whether applied
suddenly or increasing slowly.

They react to AC and pulsating DC fault
current which reach 0 or almost 0 within
one time period of the mains frequency.

Overall and Installation Dimension(mm)

 

Residual-current circuit breaker (RCCB), is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock, or if the person touches both conductors at the same time. If the RCD device has additionally overcurrent protection integrated in the same device, it is referred to as RCBO.
The ETEK range of residual current circuit breakers without integral overload protection (RCCBs), provided protection solutions to a wide range of applications.
